【表】[Detailed Description of the Invention] Field of Application This invention is lightweight and has excellent corrosion resistance as a heat exchanger member used in particularly harsh environmental conditions, such as a heat exchanger, and furthermore, it can be assembled into a heat exchanger. The present invention relates to a 3-layer or 5-layer clad plate that can be easily assembled and that the assembly process can be omitted, and a method for manufacturing the same. BACKGROUND ART With recent advances in space development, various heat exchangers are also being used in artificial satellites. Generally, Al material is used as a heat exchanger member for the purpose of weight reduction. There has been a demand for materials for heat exchangers that are lightweight and have a long life under harsh atmospheric conditions, but as in the past,
When Al is used for structural members, under harsh environmental conditions, Al is prone to pitting corrosion due to generated moisture, and if pitting corrosion penetrates the Al member, the cooling fluid will leak into other rooms. There is a risk of leakage, which poses a major problem with its reliability. Therefore, as a heat exchanger member, an Al-Ti two-layer clad plate, which is a Ti plate coated with an Al plate on one or both sides of a lightweight, corrosion-resistant and mechanically strong Ti plate, is used.
Al-Ti-Al three-layer clad plate has been proposed, but
Since the manufacturing method is hot pressing, there is a problem in productivity, and there is a problem in that the clad plate cannot be provided at a low price. In order to improve productivity, methods such as cold pressure welding and diffusion annealing, which are common manufacturing methods for clad plates, can be considered. Depending on the diffusion annealing conditions, the growth of intermetallic compounds such as AlTi and TiAl 3 at the welded interface may make the welded interface brittle and reduce its adhesive strength. In addition, depending on the thickness, purpose, and mechanical properties of the product clad plate, it may be necessary to perform cold rolling after diffusion annealing, or further intermediate annealing, finish rolling, etc. If the plate thickness ratio before welding is not appropriate, cracks and tearing will occur in the core Ti plate during cold welding or cold rolling, making it difficult to produce good-quality two- or three-layer clad plates. I couldn't get it. In addition, such a two-layer or three-layer clad board,
For example, when used in a plate fin type heat exchanger, it is used between the clad plate and the corrugated fin plate.
It was necessary to heat and press the Ag solder plate in between, which caused the problem of requiring a large number of man-hours for complicated operations such as positioning and brazing during assembly. Purpose of the Invention This invention solves the problems of conventional Al-Ti-Al clad plates, does not cause cracks in the Ti core material, can be produced with high quality at low cost, and can be assembled into heat exchangers. It can solve various problems when assembling into a heat exchanger, and save labor during the assembly process.
The object of the present invention is to provide a multilayer clad plate that can be accurately and easily assembled into a heat exchanger, and a method for manufacturing the same. Structure and Effects of the Invention The present invention provides an Al brazing layer that is applied to one or both sides of a Ti layer via an intermediate Al layer, and
The layer thickness ratio of the Ti layer, Al layer, and Al brazing layer is 1:0.1 to 4:0.005 to 0.4.
This is a three-layer or five-layer clad plate characterized in that the interface between the Ti layers is made of metal bonding. In addition, this invention provides a coating on one or both sides of a Ti plate whose surface has been cleaned.
Two layers consisting of an Al plate and an Al brazing plate with thicknesses set in advance such that the thickness ratio of the Ti layer of the clad plate, the intermediate Al layer, and the Al brazing layer is 1:0.1 to 4:0.005 to 0.4. After overlapping the Ti plate and the two-layer clad plate with the Al plates of the clad plate facing each other, they are cold welded at a reduction rate of 30% to 70%, and in the case of an Al solder-Al-Ti three-layer clad plate, , diffusion annealing is performed under the conditions of 500℃ to 560℃ in vacuum for 1Hr to 6Hr, and in the case of Al braze-Al-Ti-Al-Al braze 5-layer clad plate, annealing is performed in vacuum or in N 2 , Ar This is a manufacturing method in which a three-layer or five-layer multilayer clad plate is obtained by diffusion annealing in an inert gas such as gas at 500° C. to 560° C. for 1 hour to 6 hours. With this invention, there are no cracks in the Ti core material, and it can be manufactured efficiently and inexpensively with high quality.
Furthermore, since it has Al solder on its surface, it can save labor in the assembly process when assembling into a heat exchanger, and has the advantage that it can be assembled into a heat exchanger accurately and easily. DISCLOSURE OF THE INVENTION Based on Drawings The method for manufacturing a five-layer Al braze-Al-Ti-Al-Al braze clad plate according to the present invention will be explained with reference to FIG. While unwinding the coiled Ti plate 1, the surface is cleaned mechanically or chemically, and Al-Al is applied to both sides of the Ti plate 1, which is run rightward in the figure.
Each of the two-layer clad plates 2 and 3 made of wax
The Al layers are stacked facing each other and pressed with a pressure roll 4.
Cold welding is performed at a reduction rate of 30% to 70%. At this time, the two-layer clad plates 2 and 3 are Ti
It has a plate thickness ratio of (0.1 to 4):(0.005 to 0.4) with respect to the plate thickness. After the above-mentioned cold pressure welding, it is heated in a continuous annealing furnace 5 at 500°C to 560°C for 1 hour in vacuum or inert gas.
Diffusion annealing for ~6 hours, cold rolling with rolling rollers 6 if necessary, softening treatment in a softening furnace 7,
Alternatively, intermediate cold rolling, intermediate annealing, final cold rolling, or further softening treatment is performed to obtain an Al braze-Al-Ti-Al-Al braze five-layer clad plate. Preferred embodiment of the invention In this invention, an Al brazing plate before cold pressure welding,
The plate thickness ratio of Al plate and Ti plate is (0.005~0.4): (0.1~
4): The reason for limiting it to 1 is as follows. If the thickness ratio of Al brazing plate to Ti is less than 0.005, the Al brazing plate will be too thin and there will be a problem in brazing properties, and if the plate thickness ratio exceeds 0.4, the brazing effect will be saturated. This is not preferable because it increases the cost. In addition, if the thickness ratio of the Al plate to Ti is less than 0.1, Al and Al solder will react during brazing work, and the Al will be eroded. Furthermore, if the plate thickness ratio exceeds 4, cracks or cracks may occur in the Ti during cold welding or subsequent cold rolling, which is undesirable. In addition, if the reduction rate of cold welding is less than 30%, sufficient pressure welding cannot be achieved, and if the reduction rate exceeds 70%, Ti
This is undesirable because it causes cracks to occur in the board. Diffusion annealing conditions are less than 500℃ and less than 1 hour.
If the board is not softened enough and the temperature exceeds 560℃,
This is undesirable because Al will dissolve, and
If it exceeds this, the diffusion annealing effect will be saturated and the growth of intermetallic compounds at the pressure interface will be extremely unfavorable. In addition, as for the atmosphere during diffusion annealing, heat treatment in a vacuum is preferable because Ti easily absorbs oxygen, nitrogen, and hydrogen gas, which greatly changes the properties of Ti. When covering with an Al clad plate, or when using an as-rolled flat plate without bending or drawing in the subsequent process, diffusion annealing may be performed using an inert gas such as N 2 gas. The reduction rate of cold rolling after diffusion annealing is selected appropriately depending on the required thickness of the product clad plate, usage conditions, and required mechanical properties, but if the reduction rate exceeds 70%, the Ti plate may crack. , which is undesirable because it causes cracks. Further, the softening treatment conditions after cold rolling may be the same as those for diffusion annealing in terms of atmosphere, temperature, and time. In this invention, one or both sides of the Ti plate has a specific thickness ratio to the thickness of the Ti plate.
Although the Al plate and the Al brazing plate may be overlapped and cold-press bonded while running, the upper cladding plate consisting of the Al plate and the Al brazing plate is commercially available, and the above-mentioned two-layer cladding plate is used in the method of the present invention. is preferable. In addition, the Al brazed clad plate in this invention is
Composition: JiS BA4343, BA4045, BA4145,
BA4047 etc. are preferred. Examples Example 1 Al was applied to both sides of a 2 mm thick x 300 mm wide Ti plate that had been rewound by an unwind roller and had its surface buffed.
Total plate thickness 1mm x width consisting of 0.9mm plate and 0.1mm Al brazing plate
The Al side of a 300 mm Al-Al brazed two-layer clad plate was run while facing the Ti plate, and the two plates were overlapped and cold-welded at a reduction rate of 70% to obtain a plate thickness of 1.2 mm.
It was made into a 5-layer clad board of mm. After that, after diffusion annealing at 550℃ for 2 hours in a vacuum furnace, cold rolling was performed at a reduction rate of 70%.
A layered clad plate was obtained. A test piece was taken from the clad plate and the tensile strength, elongation, Young's modulus, volume resistivity, specific gravity, and layer thickness of each layer were measured, and the results are shown in Table 1. 【table】
